AirPlans eSIM Data Plans for South Korea

AirPlans does not provide a truly unlimited data eSIM for South Korea. Every plan labeled “Unlimited” contains a high‑speed data cap of 1 GB per day (or 2 GB per day on the “Unlimited Plus” variants) and the speed drops to a reduced rate—512 kbps or 2 Mbps—once the limit is reached. Travelers who need more data can choose from fixed‑data plans that offer larger allowances, such as the 100 GB, 90‑day plan for $237 USD or the 100 GB, 30‑day plan for $253.89 USD, though these are not described as unlimited. Selecting a fixed‑data plan may be more cost‑effective for most users unless they require very heavy data usage.

AirPlans does not provide any eSIM plans for South Korea that include a phone number or SMS capability. The available offerings are strictly data‑only plans, so travelers will not receive a local calling number from this provider.

If a traveler needs to make voice or text communications, they can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some network restrictions may affect these apps in South Korea, so it is advisable to confirm their availability before purchasing a plan.

AirPlans offers 15 single‑country plans and 66 multi‑country plans for South Korea. The single‑country options vary from about $3.20 to $50, with data caps between 1 GB and 25 GB, and run for 1 to 30 days. The multi‑country plans range from roughly $20 to $375, providing 5 GB to 100 GB of data and valid from 7 to 365 days. AirPlans’ plans are split between fixed data‑cap packages, which give a set amount of traffic to use for the entire validity period, and daily data‑cap packages, which limit the amount of data you can download each day. This mix lets travelers choose between predictable usage and flexibility depending on how they plan to move between destinations.
